    duplicate Id for a component

    Juan Ignacio Sánchez Lara Apprentice

      I was using MyFaces and I wanted to switch to JSF RI (I'd better say I've been told to). Since I've switched I get "duplicate Id for a component" errors really often, specially at rich:tabPanel-ed pages.

      Has anybody had this problem before?

          Yes!
          I had some problem for tabbed pages. But I can't to reproduce and localize this for a small example.

            Using Sun RI? Did you solve it?

              Yes, I'm using Sun RI in GlassFish v2.
              But I can't solve this for now.

                Mmm... Glasfish v2, so you'll probably be using JSF 1.2, that's supposed to be a much better implementation. People who are stuck at 1.1 are f****d up :-\

                  duplicateId is not only the problem of JSF 1.1. If you look at the lists of fixed bug for JSF 1.2 and facelets, you can find a lot of entries about fixing.

                    I'll stay with MyFaces then, it gives me no duplicatedId problem at all.

                    Thanks!

                      Good afternoon.

                      I've faced the same problem right now. Can't find a solution. I have a scrollable dataTable on my page and while it's displaying, facelets give me this error: "duplicate Id for a component staffDataTable_Form:staffDataTable:j_id33".

                      The strange thing is that I have two pages with such table with the same information in it. But only one gives me this error.

                      Here is my staff.xml (which gives the error):

                      I use JSF 1.2, Facelets, RichFaces 3.1.0.


                      Thanks in advance. Any advice would be appreciated.

                        staff.xml = staff.xhtml (sorry for that)

                        P.S.: This page opens from the page where the same scrollableDataTable is. So user goes there, selects a row, presses a commandButton and is redirected to staff.xhtml(where the error appears).

                            This could be caused by session scoped beans which holds components bindings.
